Most of Europe doesn't live in what Americans would call suburbs, but villages. They're dense where people live and have train and bus service conveniently, because in postwar Europe there were a lot fewer cars. They also zone such that there's a dense living area surrounded by farmland - when that farmland becomes all housing thenyoull have American style suburbs, but few in Europe want that because it's harder to get where you want to go.

You'd better update your knowledge.

Suburbs now spread for miles around towns and even former villages, for ten or twenty miles around major cities.

And small towns and villages lost their railways and stations 40 to 80 years ago.

Not in a lot of Germany, or Austria from what I saw driving the countryside for a week

This is pretty much the norm in orher places such as China and Japan.

New developments havebeen getting more sprawl in China though, as cars have become more popular.

Post-war Europe didn't have cars and cities are surrounded by farmland? Nope.
